This paper presents an analytical design method for the dc collector systems of offshore wind farms and proposes an improved topology to overcome the limitations of the conventional series–parallel (SP) topology. During a severe failure in the SP topology, bypassing the faulty units imposes overvoltage on fault-free units and leads to the disconnection of the series branch from the collector system...
This paper deals with dynamic modelling and control of wind power units in an offshore wind farm with a de system, consisting of permanent magnet synchronous generators, diode-bridge rectifiers and dc/dc converters. Such an integration offers a robust structure well-suited for offshore wind power applications. A simplified yet accurate model for a wind power unit is proposed and validated for the...
